How high should I rev the motor to? I remember seeing 7500 is the max but other people say they go to 8500,but I dunno if that is with a 2.0 block maybe.I have a 2.4 block and 2.4 crank,so how high will it go?

 

8000 max... its not really the strength of the crank (to a point) however an issue of piston speed due to rod/stroke ratio... additionally most set ups will have a nosedive in power after 7500 rpm anyway so there is no need to rev it out...

 

You can figure most major tuners will agree that a 2L is safe to rev 4th out to 10,000..

The 2.4's piston speed will be about 15% faster than a 2L at the same rpm. 8,500 is a safe bet on a stock mitsu 4g64 crank, manley TT's and wiseco pistons.

I have no experience with the aftermarket cranks. All i have personal experience is with the above combo.

Shep explained this to me back in 2005 that he was revving a 2L to 12,00 i should have no problem at 9k. Back then everyone on the forums was soooooo against going over 7k on a stroker and strokers werent suppose to last nearly as long as 2 liters.

Well now its 2011 i'm on the same motor. And i'm here to say 8,500 daily on my daily driver with more miles than mosts chassis is very safe.

A good cam, stock headed 35r car will not nosedive at 7500.

 

2.0L- 10,800 is the same as a 2.4 at 9500, but the 2.0L will have higher mean acceleration (G force) for the same piston speed since it is still turning faster. 2.3s have been revved to 8500 since DSMs, there is no reason an Evo 2.3 will turn less other than it doesnt have enough turbo.

 

hmm...
